Abstract

The invention relates to the management of vascular patency by the use of implanted devices delivering one or more energies to a target vascular tissue wherein such energy delivery sources are substantially located in the vicinity of a target vascular region. The invention preferably employs electric currents as energy and utilizes one or more electrodes positioned in the vicinity of a target region and one or more electrodes located elsewhere. Such devices may be useful in the management of stenotic lesion formation adversely associated with a loss of patency in a variety of disease states or conditions, including vascular patency needed for hemodialysis used in the treatment of kidney failure.
